A trajectory data publishing algorithm satisfying local suppression
International Journal of Distributed Sensor Networks, 2021 Suppressing the trajectory data to be released can effectively reduce the risk of user privacy leakage. However, the global suppression of the data set to meet the traditional privacy model method reduces the availability of trajectory data.

A Privacy Risk Model for Trajectory Data [PDF]
, 2014 Time sequence data relating to users, such as medical histories and mobility data, are good candidates for data mining, but often contain highly sensitive information. Different methods in privacypreserving data publishing are utilised to release such private data so that individual records in the released data cannot be re-linked to specific users ...
